"That offer meant a lot," said Harrison. "I was very surprised. They came out of the blue. After the conversation, I was very happy that they offered. I was happy that they offered. Coach (Brian) Polian offered and he said they'd figure out what side I'll play when I got out there. But that offer is a great opportunity to do big things."
Harrison has double-digit offers and said a few of them are standing out.
He's building relationships with assistants at each school but said the Huskies have had head coach Chris Petersen as his primary recruiter.
"It has mainly been Coach Pete at Washington," said Harrison. "That means a lot. He's a nice guy and he wants to help me and my future and be there as a supporter for me."
Two Washington natives are recruiting him at Cal.
"Coach (Nick) Edwards and Coach Tui (Marques Tuiasosopo) are recruiting me at Cal," said Harrison.
For UCLA, it's former Husky linebacker and current Bruin linebackers coach Scott White.
"Coach Tui was who offered me at UCLA but now Coach White is the one recruiting me," said Harrison.
And at Michigan, its area recruiter Jay Harbaugh.
"Coach (Jay) Harbaugh is the main one I talk to at Michigan.
Harrison said he's still in no hurry to make a decision.
"I plan to take all five of my visits and I'm in no rush to make a decision," said Harrison.
